Sabancı Central Mosque (Turkish: "Sabancı Merkez Camii" ) in Adana is the largest mosque in Turkey. The exterior of the mosque (and its interior decoration) is similar to the Selimiye Mosque in Edirne, though it has six minarets, similar to the Sultan Ahmed Mosque (Blue Mosque) in Istanbul.

Can we draw the following conclusion?
The largest mosque in Turkey was the Blue Mosque until the Sabanci Central Mosque was built and has six minarets that are similar to the Sultan Ahmed Mosque.
It's impossible to say
